Seriously - you SAW it at the MGM in Vegas? I am headed out there for six days in a week or two - I will be looking for it in every bar on the strip as well as Freemont, particularly at Red Square in Mandalay Bay. Finding it available will be sweet.
I won't be posting much from Vegas but will let the board know IF I find it, as well as if anyone has heard of it (as I will mention it everywhere I stop - should cover about 40 locations).
As for quality, it's smooth for sure; for my taste does not replace my 'go to' (Tito's)...
